Very fast, more than I thought! Very convenient to make spaghetti vegetables in 2 times 3 movements, slice perfectly, but it lacks a star as it is not shown or explained anywhere that during use, he released some sort of vegetable cylinder, namely zucchini, by a hole that should be used to maintain the vegetable in place. It's not a big loss but it's just very surprising at first use or even worrying given the complete absence of such information in the manual or on pictures. I highly recommend to all who like to vary their gustatory pleasures!
